Wang, Weiming (author), Liu, Yong-Jin (author), Wu, J. (author), Tian, Shengjing (author), Wang, C.C. (author), Liu, Ligang (author), Liu, Xiuping (author)Offsetting-based hollowing is a solid modeling operation widely used in 3D printing, which can change the model's physical properties and reduce the weight by generating voids inside a model. However, a hollowing operation can lead to additional supporting structures for fabrication in interior voids, which cannot be removed. As a consequence...journal article 2018
